"This water-cooling kit has been custom picked by me, I chose probably some of the higher end parts dangerden has to offer. This gave me the performance I predicted. Dangerden has done a fantastic job with their Maze 4 gpu blocks, and the luctite water-cooling blocks. The black ice extreme radiator is of high quality and the 5 1/4 bay reservoir looks nice and does not produce any noticeable noise. The only real problems with these parts were the noisy pump and the terrible paint job on the pump's bottom."
